WebbRR from the oximeter pleth was derived as previously described.11 16 In summary, the pleth signal was low-pass-filtered using a filter with a cut-off frequency at half the median HR calculated over 1 min epochs; this filters out the HR output but leaves the RR component.12 The data were then visually analysed using a signal browser that … WebbOf note, in the face of a low signal (or low perfusion) some oximeters may auto adjust the scale of the display (y axis) to increase the visual amplitude of the pleth. This can be misleading to clinicians who must also pay attention to signal quality indicators when available.
